Active clinical trials for "Body Weight"

Study DFA102E is an extension of Study DFA102, which included a 28-week treatment period with randomized study medication. The purpose of the extension study is to examine the long-term (up to 1 year) safety, tolerability, and effect on body weight of treatment with pramlintide and metreleptin, administered as separate subcutaneous (SC) injections, in obese and overweight subjects.

Study design: Double blind, randomized, placebo controlled study.The proposed study will consist of two main segments: Segment 1 is aimed to assess the effect of 6-12 months treatment with nutritional supplementation standardized formula, in short and lean prepubertal children on weight SDS, height SDS, BMI SDS and growth velocity Segment 2 is aimed to explore the eating behavior of idiopathic short stature and lean prepubertal children against their sibling who have a normal height and body weight and to find out whether there is a difference in eating patterns and quality of life between idiopathic short stature and lean prepubertal children and children with normal height and body weight Segment 1 Population: 200 subjects and controls will be recruited to segment 1 of the proposed study, 100 at each group. Participants will be recruited from healthy children who will be referred to either the institute for endocrinology or the gastroenterology unit, at Schneider Children's Medical Center for growth assessment, due to low height and weight, in whom, no gastrointestinal morbidity or other underlying cause was found. Methods: Randomization & Blinding: Participants will be randomly assigned either to the intervention group or the placebo control group. Randomization for the two study groups will be made in a ratio of 1:1. Both participants and study team will be blinded to the type of treatment that each patient will receive during the first 6 months of the study. Treatment: Participants in the intervention group will be treated with a nutritional supplementation standardized formula.Participants in the control group will be instructed to consume the same volume of formula as was calculated if they were in the intervention group. Treatment duration: The study will be divided into two treatment periods: 6 months of intervention versus active placebo followed with additional 6 months (an extension period), in which participants at the intervention group will be offered to extend the intervention period and participants at the control arm will be offered to switch to the intervention group. Study Schedule: Follow up visits will take place at 0, 3, 6, 9 and 12 months and will include: Demographic data, medical history and growth data (month 0): Demographic parameters, including birth date, gender, birth weight and length for gestational age, medical history and growth data, including height velocity, parent's and sibling's weight and height will be documented from patient's file. Nutritional assessment Anthropometric assessment (months 0, 3, 6, 9 12): Height without shoes Length Weight with light cloths and without shoes MAC Body mass index (BMI) will be calculated from children's weight and height and age and gender specific BMI SDS will be calculated Body composition assessment using the method of bioelectrical impedance Laboratory parameters (months 0, 6 and 12): Sleeping Questionaire Segment 2: 86 subjects and controls will be recruited to segment 2 of the proposed study Population: Short and lean prepubertal children participating at segment 1 of the study and who are at study entry under 10th percentile in height, when the weight percentile is equal or smaller to the height percentile. Only participants from segment 1 who have siblings with normal height and body weight for age and gender, will be able to participate in segment 2 of the study Control group 1: Sibling of participants in segment 1 of the study, who have a normal height- above 25th percentile and normal BMI for age and gender- above 5th percentile and under 85th percentile. Control group 2: Healthy children from the community who have a normal height above 25th percentile and normal BMI for age and gender above 5th percentile and under 85th percentile Segment 2 of the study will be designed as a case- control study and will focus on the eating patterns, sleeping patterns and quality of life of participants at segment 1 at time 0 month of the study, before the beginning of the nutrition intervention. These findings will be compared to data of a control group, which will be comprised of siblings of participants in segment 1, with normal height and body weight which are matched in age.

The aim of this study was to investigate the effects of gait training on ground level, combining BWS and FES in people following chronic stroke.

This is a randomized controlled trial of the effects of chewing gum on body weight. The investigators will randomly assign 200 overweight or mildly obese adults to one of two groups. Participants must be otherwise healthy and ages 19-50. The control group will receive only printed information on optimal diet and increasing physical activity. The intervention group will be instructed to chew gum following meals and in place of snacks for a minimum of 90 minutes per day. The intervention group also will receive the same information on optimal diet and increasing physical activity as the control group. In this 8-week intervention, the primary outcome will be change in body weight, and secondary outcomes will be changes in body mass income (BMI), waist circumference, and blood pressure. The protocol includes 3 clinic visits to assess outcomes: baseline, 4 weeks after randomization, and 8 weeks after randomization. Adherence to the gum chewing protocol will be assessed at clinic visits and during 2 telephone calls at 2 weeks and 6 weeks post-randomization. The investigators' hypothesis is that gum-chewers will lose more weight than those who receive information only.

Protein-rich diets appear to show some benefits in promoting weight loss. It is thought that increased intake of leucine may account for some of this effect. This study is designed to assess whether any of the beneficial effects of dietary leucine supplementation observed in mice also apply to humans. Specifically, our team would like to determine whether oral leucine supplementation in overweight/obese humans increases metabolic rate, reduces body weight, improves glucose utilization and/or, reduces circulating fat levels in the blood. We hope that the results obtained from this pilot study will highlight the specific aspects of metabolic improvement associated with increased daily leucine intake. This study will should provide data that can be used to design more definitive trials with regard to dietary leucine supplementation. Hypothesis This pilot study is designed to accomplish the following two goals: to assess whether any of the beneficial effects of dietary leucine supplementation observed in mice also apply in humans. Specifically, we want to determine whether oral leucine supplementation in overweight/obese individuals' increases basal metabolic rate, reduces body weight, improves glucose tolerance and/or insulin sensitivity, and/or reduces circulating Low-density Lipoprotein (LDL)-cholesterol levels. To provide data that can be used to design more definitive trials with regard to dietary leucine supplementation. We hope that the results obtained from this pilot study will highlight the specific aspects of metabolic improvement associated with increased daily leucine intake. This would in turn lead to more rigorous clinical trials involving larger sample sizes, and with diverse populations of different gender, age, and ethnic groups. Future trials may also be directed to determine minimal doses and durations of leucine supplementation that are capable of achieving clinically significant improvement in the cardio-metabolic risk profile in people.

Study hypothesis: High protein diets have been shown to make people full and and help to retent of muscle mass. This study was designed to determine effects of a protein- enriched meal replacement (MR) on weight loss and muscle mass retention by comparison to an equal calorie carbohydrate-enriched MR. Methods: Single blind, placebo-controlled, randomized outpatient weight loss trial in 100 obese men and women comparing two equal calorie meal plans.,1) 2.2 g protein/kg of LBM per day [high protein diet (HP)] or 2) 1.1 g protein/kg LBM/day standard protein diet (SP). Body weight, body composition, and lipid profiles were measured at baseline and 12 weeks.

Pioglitazone, a drug used in treatment of type 2 diabetes has been shown to improve insulin sensitivity in skeletal muscle, liver, and fat cells. Despite the beneficial effects of pioglitazone to improve insulin sensitivity and reduce cardiovascular disease in high risk type 2 diabetic patients, weight gain has been a limiting factor. Exenatide, another agent used for treatment of T2DM, improves glycemic control and promotes moderate weight loss. In this proposal we will examine the effect of combination therapy with pioglitazone plus exenatide on body weight, fat topography, beta cell function, glycemic control, and plasma lipid levels in subjects with type 2 diabetes mellitus compared to treatment with each drug separately. Assessment of beta cell function will be performed by measuring the maximal insulin secretory capacity using a maximal hyperglycemic stimulus combined with an intravenous arginine stimulus.

The purpose of this research study is to test the safety and efficacy (how well it works) of exenatide as a treatment for weight gain associated with olanzapine in obese adults with Bipolar Disorder, Major Depressive Disorder, Schizophrenia or Schizoaffective Disorder Exenatide has been approved by the FDA for the treatment of Type 2 diabetes. It has not been approved for the treatment of weight gain associated with olanzapine in obese adults with bipolar disorder, Major Depressive Disorder, Schizophrenia or Schizoaffective Disorder

The purpose of this study is to examine the effect that betahistine has on body weight in obese subjects.

This pilot study is a randomized, controlled clinical trial to compare anthropometric and metabolic changes associated with six months of weight management by means of a very low carbohydrate diet or a calorically-restricted low fat diet. We hypothesized that the low fat diet would be associated with more weight loss and improvement of cardiovascular risk factors than the low carbohydrate diet.
